First, let me just say that I LOVE this plugin! It does what I need, it does it well, and it has all the primary social media sites, WITHOUT my having to disable 40 not-so-common sites that my readers aren't using, anyway.
I'd love to see the ability to leave the buttons at both the top and bottom of the post, but only include the prepended text at the bottom. It gets a bit cluttery to have the wording at the top. But it seems to boost shares to have the buttons visible there.
